Although there's more than one definition of "the South Pole", the most popularly accepted one (and a travel destination) is a fixed location in the southern hemisphere at the Earth's axis of rotation, latitude 90°S (longitude not applicable). Unlike the North Pole, which is nothing but a sheet of ice floating on the surface of the Arctic Ocean, the geographic South Pole is located on solid ground, allowing a permanent research station to be built at the site of the pole itself. Although it was once an elusive goal that took the lives of many explorers, thanks to modern technology, it has been permanently staffed since 1956, and is now a destination of commercial travel expeditions.

"The South Pole" is also defined geomagnetically. This pole drifts around, and since there's nothing particularly interesting about it other than perhaps watching your compass not work, it receives no visitors. There's also a southern pole of inaccessibility, the point in Antarctica farthest from any coastline. This is a fixed location (barring major sea level changes that might redefine coastlines) at 85°50'S 65°47'E, but as the name suggests, travel to this point is generally impractical.

The first persons to successfully reach the south pole were the 5 men of a party led by Roald Amundsen, who reached the pole on December 14, 1911. A competing British team led by Robert F. Scott reach the pole on January 17, 1912, but ran short of supplies and died of starvation or exposure 11 miles from their last supply depot. A US Navy plane with 2 aboard flew over the pole on November 29, 1929.

No one stepped foot on the south pole until 1956, when another US Navy plane reached the pole, landing this time. Soon thereafter, the US constructed a station as part of the International Geophysical Year, which has been permanently staffed since.

It's tempting to say that the climate at the South Pole is consistently cold, but it is not. In December it is very cold, with an average temperature of around -28℃ (-18℉). However In July it is astonishingly cold, with temperatures sagging to -80℃ (-112℉). (Note that there are no "day-time highs" or "night-time lows" in these figures, because the sun only sets and rises once each year.) Snowfall is scarce; since weather systems rarely penetrate into inland Antarctica and because the temperature is often too low, hence its desert status. The existing snow does drift, however, with winds averaging a modest 12 knots. (At these temperatures, calculating wind-chill factors is fairly pointless.) Antarctica is the coldest, windiest continent on Earth and as such an expedition there surely carries a risk of danger. Freak snowstorms and white conditions (both caused by high winds) can affect South Pole expeditions and have buried the ceremonial South Pole markers (they have to be bulldozed out of the snow usually).

The terrain around the South Pole is consistently flat. Ice is fluid enough to settle to a flat surface if left undisturbed, and the underlying rock isn't geologically active, nor is there any rainfall to sculpt it.

Antarctica is (for obvious reasons) the least-visited continent, and the South Pole is (because it is not accessible by sea) the least-visited site in Antarctica that is nominally "open to tourism".

Most expeditions take place in November thru January, during the Antarctic summer/day. They generally launch from Punta Arenas at the southern tip of Chile, stop at Patriot Hills camp in the Ellsworth Mountains on Antarctica, and make the final leg of the trip by air as a day trip to the Pole itself. Some expeditions drop travelers well short of the Pole, leaving them to finish on the ice.

From nov-2013. All companies have the same new price 45.000 US $, and increasing....

Adventure Network[1]. Offers flights several times a year for a chilly US$45,800 per person. Also offers guided treks by ski to the South Pole. Covering the full 1170km from coast to Pole involves an estimated 65 days of skiing, for about 7-9 hours a day, hauling a sled weighing 110-130 lbs (50-60 kg), and the price for the privilege is US$60,500. Alternatively, you can cheat and fly halfway there with the "Ski the Last Degree" package, in which case you'll ski for only about two weeks and pay a mere US$58,900.

Arctic Odysseys. [2]. Offers a 10-day excursion to Antarctica, including a day at the Pole.

Icetrek, [3]. Offers a week-long excursion by air with one day at the Pole (US$33,500), and 15- to 25-day expeditions cross-country skiing the last 1 or 2 degrees (starting at US$38,500).

PolarExplorers, [4]. Offers a two-week expedition skiing the last degree to the Pole. US$37,500.

Voyage Concepts, [5]. Offers a two-week excursion by air with one day at the Pole, and a 25-day expedition (including all travel time and stopovers) skiing the last degree to the Pole and flying back. Departs from London by way of Buenos Aires. $42,450 and up.

Extreme World Races, [6]. EWR organises races at the extreme of human performance. 'Race to the South Pole' this year is being organised to mark the 100th Anniversary of the Amundsen-Scott race to the South Pole.

The current modular elevated station with the ceremonial South Pole behind it and the geodesic dome to the right

There is a ceremonial south pole at Amundsen-Scott South Pole Station, consisting of a metal sphere on a red and white pole, partially surrounded by the flags of the signatories of the Antarctic Treaty. Although great for photo opportunities, it is actually about 300 meters from the exact loction of the South Pole.

The geographic south pole is marked by a simpler rod with a head on it. The rod's head is made of brass, and is designed and moulded on-site. The ice on which the station sits shifts about 10 meters annually, and a new marker is added each year in a small ceremony. There is also a sign bearing quotes from the journals of Roald Amundsen and Robert F. Scott, leaders of the first two successful expeditions to the South Pole. (Scott's party arrived 34 days after Amundsen's, and died on the return trip.)

There are three generations of structures at the site: The Old Pole, the original wooden station, built in 1956 and abandoned in 1975, now buried by drifting snow, off-limits for safety reasons. The metallic Geodesic Dome built in the early 1970s, 50 meters wide and 16 meters tall, enclosed several modular buildings, but was decommissioned in 2008 and completely disassembled in 2009-2010. The spot it formerly occupied is now pretty much indistinguishable after snow drifted in to cover it. The brown Elevated Station begun in 1999, a modular structure built on stilts to prevent snow from accumulating around it. Semicylindrical metal "arches" next to the dome serve as storage, power plant, and vehicle shop; they're connected to the main station via a 6-story unheated metal tower officially termed the "vertical tower" on the drawings, but known around station as the "beer can".

A Visitor Centre was erected on-site to cater for the few visitors the base receives. It was opened in response to pressure from visitors to be allowed into the official research building, which is technically forbidden. The centre is no more than a small tent-like structure.

Ask for a tour of the station from staff. Some staff volunteer to be tour guides for visitors, so you may be able to get a tour of the Elevated Station. It is very unlikely that you will be allowed to visit the South Pole Telescope (SPT), the Atmospheric Research Observatory (ARO), or the Ice Cube Lab Neutrino Detector (ICL). These are working research facilities and do not allow tourists. You will not be allowed to walk around un-escorted on the base as it can be dangerous to those who do not know the area or hazards. Safe areas for camps are located near the visitor center between SPT, ARO and the Elevated Station.

In late December an ice sculpture contest is held by station staff and researchers. Some beautiful and whimsical ice art can be created. The sculptures are displayed until the closing of the station in early February, when they are destroyed to prevent the formation of snow drifts during the winter.

Frisbee golf—"holes" are sometimes set up around the base to play frisbee golf...if you can handle the temperatures!

Although they are not in the habit of accommodating visitors, the facilities of Amundsen-Scott station can provide shelter in the event that weather prevents you from returning to your base at the end of your day visit.

All of the health and safety advisories for Antarctica in general apply to the Pole.

Although the ground at the South Pole is close to sea level, the thick ice at that location raises the station to an altitude of 9,300 feet (2,835 meters). And because the earth's rotation causes the atmosphere to thin out at the poles, the air pressure is more like at 11,000 feet. So in addition to preparing for the coldness and dryness of the air, travel to the Pole also requires acclimatization for high-altitude travel. (See the Altitude sickness article for more.) The altitude also makes the danger of UV exposure even greater than at the Antarctic coast.
